Most of HEV are built using existing engines. These engines have been developed for conventional car and are not especially tailored for HEV. The objectives of this work are to establish general requirements placed on an ICE for a HEV application, to draw the main characteristics of the engine and to find the best configuration of twin-cylinder ICE to motorize an HEV. The twin-cylinder engine offer interesting perspectives in the field of HEV thanks to its small size, low weight and low cost. [less ▲]

The presence of antibacterial in 97 pork and 83 chicken meat samples, randomly collected from 3 different representative provinces (Hanoi, Hai Duong and Thai Binh) of the Red River Delta, was determined by a screening step using in parallel 2 microbiological methods (Premi®-test and New Two Plate Test). In total, 27% of all samples displayed a positive response in at least one of both tests, from which 11 (13% of chicken samples) are chicken samples and 38 (39% of pork samples) are pork samples. The 33 samples from the Thai Binh which were screened positive were then submitted to post-screening tests specific for tetracyclines and (fluoro) quinolones (Tetrasensor® dipstick for tetracyclines and an ELISA for quinolones), two groups of antibiotics widely used in animal production in this region, and confirmed by liquid chromatography coupled to mass spectrometry. Tetracyclines and (fluoro)quinolones residues were found, using a post screening test, in 23 and 5 samples, respectively. Ten (all pork) and 4 samples (1 pork, 3 chicken) were confirmed containing tetracyclines (chlortetracycline, oxytetracycline, tetracycline, doxycycline) and (fluoro) quinolones (nalidixic acid, enrofloxacin and ciprofloxacin) respectively, from which 1 and 3 pork samples were found to contain enrofloxacin and tetracycline residues , respectively, with a concentration higher than their respective MRLs. This study shows the good performance of the proposed strategy to identify non-compliant meat samples (microbiological screening, tetracyclines and quinolones targeted post-screening and confirmation), which allows to obtain conclusive results in 82% of the cases.

This paper describes the work realized at the "Centre Europeen d'Archeometrie" to highlight the utility of high-energy alpha PIXE in the particular field of archaeometry and to introduce the developments done and to be clone to complete the knowledge of high-energy alpha PIXE. It starts with the comparison of the yield and the noise background between several alpha particle beams and the comparison between alpha particle and proton beams on different thick and thin references. After, this paper depicts the developments done at the "Institut de Physique Nucleaire, Atomique et Spectroscopie" to perform such high-energy experiments, first on standards and later on cultural heritage objects. Moreover, it introduces the problematics of such beams for the quantification in PIXE by the intermediary of the knowledge of the ionization and X-ray production cross-sections and also the developments done to answer to this serious lack in the databases.

The Ligurian Sea, part of the Cetacean Sanctuary, is known to be a productive area hosting many marine mammal species of the Mediterranean Sea. Investigations on trophic relationship and pollutant monitoring are of primary importance for their conservation. As isotopic composition of an animal is related to that of its prey, ð13C and ð15N were measured by mass spectrometry in muscle of 12 striped dolphins (Stenella coeruleoalba), 1 bottlenose dolphin (Tursiops truncatus), 2 fin whales (Balaenoptera physalus), 3 Risso's dolphins (Grampus griseus), 1 Cuvier's beaked whale (Ziphius cavirostris) and 1 juvenile sperm whale (Physeter macrocephalus) stranded along the Ligurian coasts between 1991 and 2004. Hg concentration was also analysed in marine mammal liver by spectrometric absorption. Through ð13C and ð15N measurements, two marine mammal groups appeared: the first group characterised by high ð13C and ð15N values (mean values: -17.5‰ and 11.0‰ respectively) included the sperm whale, the bottlenose dolphin, the Risso’s dolphin and the beaked whale. The second group including striped dolphin and fin whale displayed lower mean ð13C than the first group (-18,48‰), with the fin whale showing the lowest ð15N value (8,8‰ ± 0,7). Our isotopic data are in good agreement with previously described feeding habits: the first group obviously fed at a higher trophic level and in more coastal waters associated with the continental slope while the second fed offshore, with the fin whale occupying the lowest trophic position. Hg concentrations reflected a similar pattern, with the lowest value observed in the fin whale (mean value: 0.1 µg.g-1 dw) and the highest in both the bottlenose dolphin (3769 µg.g-1 dw) and the Risso’s dolphin (1363 µg.g-1 dw). However, beside trophic position, numerous factors might be involved in Hg accumulation in marine mammals such as the age, body condition and specific metabolism. [less ▲]

We present the results of about a decade of efforts toward building an empirical mass distribution for hot B subdwarf stars on the basis of asteroseismology. So far, our group has published detailed analyses pertaining to 16 pulsating B subdwarfs, including estimates of the masses of these pulsators. Given that measurements of the masses of B subdwarfs through more classical methods (such as full orbital solutions in binary stars) have remained far and few, asteroseismology has proven a tool of choice in this endeavor. On the basis of a first sample of 15 pulsators, we find a relatively sharp mass distribution with a mean mass of 0.470 M⊙, a median value of 0.470 M⊙, and a narrow range 0.441−0.499 M⊙ containing some 68.3% of the stars. We augmented our sample with the addition of seven stars (components of eclipsing binaries) with masses reliably established through light curve modeling and spectroscopy. The new distribution is very similar to the former one with a mean mass of 0.470 M⊙, a median value of 0.471 M⊙, and a slightly wider range 0.439−0.501 M⊙ containing some 68.3% of the stars. Although still based on small-number statistics, our derived empirical mass distribution compares qualitatively very well with the expectations of stellar evolution theory. [less ▲]
